The Callaway Plant received an Operating License on June 11, 1984. This report presents the analytical data from the l'; environmental monitoring programs with appropriate ,

interpretation for 1989 and the environmental evaluations for plant modifications completed-during 1989.

The third section of this report summarizes and-interprets the reuults of the radiological environmental monitoring program conducted in accordance with Technical Specification I. Section.3/4.12. .Section four: describes non-radiological environmental' monitoring-and its results conducted in accordance with Section-2,2 of Appendix B to the callaway I Operating License. The-fifth section of this report describes changes in plant design or operation, tests, and experiments made in accordance with Section 3.1'of Appendix B

~

of the Callaway Plant Operating License.

2.0 CONCLUSION

l- The third section of this report contains all.the I radiological environmental monitoring conducted in the vicinity of the Callaway Plant during 1989. The comparison of the results for the radiological environmental: monitoring i 5 conducted during 1989 to the preoperational data and data

.5 from previous years of operation showed no unexpected or adverse effects from the operation of the Callaway Plant on the environment.

~

The non-radiological monitoring conducted in the vicinity of the Callaway Plant during 1989 is contained in section four i~ of this report. The monitoring conducted during 1989 showed no evidence of effects of drift from the cooling tower. 'The foliar disease found in the vegetation during 1989 could be  ;

directly attributed to natural causes. -

l There were no plant modifications completed during 1989'with an unreviewed environmental question as shown in section five of this report.

This report presents the data obtained from analysis of environmental samples collected through'the Callaway Plant I.- Radiological Environmental Monitoring Program (REMP) in 1989. '

Evaluation of radiation levels in the environs around Union Electric Company's (UEC) Callaway Plant entailed sampling at-strategic points in.various exposure pathways. The following types of samples were collected and analyzed: milk, vegetation, surface water, well water, bottom sediment, bedload sediment, 4

I- washload sediment, fish, airborne particulates, airborne radioiodine, direct radiation (TLD) and soil.

Analytical,results are presented and discussed along with other pertinent information. Poselble trends and anomalous results, as interpreted by Union Electric Company personnel, are discussed.

g 1.0 Introduction I

This report presents an analysis _of the results of the REMP conducted during 1989 for1 Union Electric Company, '

Callaway Plant.

In compliance with federal and state regulations and in its B, concern to maintain the quality of the_ local environment j

UEC began its radiological monitoring program in April, 1982. .

The objectives of the REMP is'to monitor potential critical j pathways of radioeffluent to man and to determine .

radiological impact on.the environment caused by operation -

of the Callaway Plant. ,

The Callaway prant consists of one 1246 MWE pressurized .

water reactor, which achieved initial criticality on october

'2, 1984. The plant is locatedLon a plateau approximately- g,

-ten miles southeast of the City of Fulton in Callaway g1

. County, Missouri and approximately eighty miles west of the St. Louis metropolitan area. The Missouri River flows by the site in an easterly direction approximately five mileo south of tha site at its-closest point. -;

2.0 Radiological Environmental Monitoring Program 2.1 Procram Design .

1 The purpose of the operational REMP at the Callaway. Plant is i to assess the impact of plant operation'on the enviro.. ment.  !

For this purpose samples are collected from waterborne, l airborne, ingestion and direct radiation pathways. Sampling ';

media are selected which are likely to show effects of plant "

effluents and which are sensitive to changes in radioactivity levels. The-types of sample media collected are: milk, surface water, groundwater, shoreline' sediment, i bottom sediment, bedload sediment, washload sediment, soil,  ;

fish, vegetation, airborne particulate, airborne radiciodine  ;

and direct radiation (TLD). i Samples are collected by Union Electric personnel and ,

shipped to Teledyne. Isotopes Midwest Laboratory (TIML)

for analysis. TLD's are analyzed by Union Electric Personnel. The data obtained are reported monthly and ,

summarized in the annual report.

Environmental sample locations are divided intb two types, I indicator and control. Indicator samplen are-those collected from locations which would be expected to manifest E

5 plant effects, if any. Control samples were collected at locations which are expected to be unaffected by plant g operation.

g 2 J

d 2.2 Precram Description Sample locations for the REMP are shown in Figures l'and 2.

Table I describes the sample locations, its direction and

[ distance from the plant, which.are control and which are indicator locations, and the types'of samples. collect at each location. Sample collection frequencies for each.of the monitoring. locations are given in Table II. The

{ collections and_ analyses that comprise the program are described in the following'pages.

In addition, a monthly grab sample is collected from one location (SO3).near St. Louis City water intake. The.

samples are analyzed for gross alpha, gross' beta,, '

tritium, Strontium-89, Strontium-90, and by gamma  !

spectrometry.

Well Water Well water samples are collected monthly from two on-site wells (F05 and F15) and one off-site wel'1 used for drinking water (D01). The on-site well water samples are collected using a_ manual grab. sampler which is lowered into the well. The off-site well water sample-is collected from a faucet after allowing the i line to flush for two minutes. Well water samples are analyzed for gross alpha, gross beta,> tritium, I strontium-89, strontium-90, and gamma emitting -

s e Washload Sediment Washload sediment sampling is performed quarterly by collecting six gallons of surface water at two

( indicator locations.(C and D) and at one control location (A). The water samples are placed in a settling flask to allow the suspended solids to ,

settle out. The solids collected are analyzed for gross alpha, gross beta, gamma isotopic, strontium-89, and strontium-90.

Bedload Sediment Bedload sediment samples are taken quarterly by submerging a hose to the bottom of the river and collecting four gallons of water at the same locations as washload sediment. Tho samples are placed in a settling flash to allow the suspended solids to settle out. The solids collected are analyzed for gross alpha, gross beta, strontium-89, strontium-90, and gamma isotopic.

Bottom Sediment Bottom sediment samples are collectad quarterly at the same locations as washload sediment. The samples are taken from water at least 2 meters rieep to prevent influence of bank erosion. A Fonar dredge is used to obtain the samples, all of which consist of the j uppermost layer of sediment. Each sample is placed, l without presertative, in a plastic bag and sealed. l Bottom sediment samples are analyzed for gross alpha, j gross beta, Strontium-89, Strontium-90, and gamma isotopic.

Shoreline Sediment Shoreline sediment samples are collected semi-annually from one indicator location (C) and one control <

location (A). The samples are collected within two feet of the waters edge and consist of 2 six inch diameter by 2 inch deep sediment plugs. Each sample is placed in a plastic bag and. sealed. Shoreline sediment samples are analyzed for gamma isotopic.

2.2.2 Airborne Pathway Airborne Particulates Airborne particulate samples are collected on 47mm i diameter glass fiber filter type A/E (99 percent removal efficiency at 1 micron particulate) at a volumetric rate of one and one half (1.5) cubic feet per minute at five (5) locations. The particulate j 15 i

__ . _ _ _ _ _ _ _ _ . ._ _ .- l

filters are collected weekly and shipped to TIML for analysis. The filters are analyzed for gross beta activity approximately five days after collection to allow for decay of naturally-occurring short-lived radionuclides. Quarterly compositen of filters by location are gamma-scanned and analyzed for Strontium-89 and Strontium-90. Four of the five , g' locations are indicator locations (A1, A8, A9, and B3) g and one location is a control location (A7). One of the indicators (A9) is located at the community with the highest D/,Q. ,

Airborne Iodine i Each air sampler is equipped with a charcoal cartridge in-line after the particulate filter holder. The charcoal cartridge at each location is collected at the g-same time as the particulate filter and analyzed for g iodine-131 within eight days after rollection.  ;

2.2.3 Ingestion Pathway Milk ,

Two gallon milk camples are collected semi-monthly during the pasture season (April through September) and monthly during the winter from one indicator location n (MS) and one control location (M1). The indicator g location supplies goat's milk and the control location '

supplies cow's milk. The milk samples are shipped in ice chest to be received by TIML within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> of l collection. Analyres for iodine-131, elemental W calcium, strontium-89, strontium-90, and gamma emitting nuclides are performed on all milk samples. ,

Fish The five most abundant fish species are collected .

monthly at two indicator locations (C and D) and at one control location (A). The fish samples are. filleted .

and the fillets are analyzed for gross alpha, gross g beta, strontium-89, strontium-90 and gamma isotopic. E Ve5Letation Monthly, during the growing season, green leafy vegetation is collected from two Indicator locations (V6 and V7) and from one control location (V1).

Vegetation samples consisted of mustard greens, turnip greens, cabbage, lettuce, and spinach. Tne vegetation ,

samples are analyzed for gross alpha, gross beta, 3.

Once a year soil samples are collected from ten indicator locations (F1, F2, PR3, PR4, PRS, F6, PR7, F8, F9 and PRIO) and one control location (V3). To ensure that only the most recent deposition was sampled, only the uppermost two-inch layer of soil was taken at each location. Sampling consists of 2 six inch square soil plugs. The litter at the surface and the root mat are considered part of the sample. The samples are placed in plastic bags and sealed. Each soil sample is analyzed for gross alpha, gross beta, and gamma isotopic.

2.2.4 Direct Radiation e

Thermolumine. scent _Dqsimetry Thermoluminescent Cosimeters (TLD) are employed to determine direct raidiation levels in and around the Callaway Site. Panasonic model UD-914 TLD's sealed in plastic bags are placed in polypror/lene mesh cylindrical holder 9 at fifty two lo ations and exchanged quarteriy and annually. Fifty of the fifty two locations are indicators (2 through 33 and 35 through 52) and two locations are controls (1 and 34) 2.3 P_rogram Execution The program was executed as described in the preceding section with the following exceptions;

1. No milk samples were available from location M5 during the months of January, February, March, November and December due to non-production of milk by the goats.

2. There were no air particulate nor airborne iodine samples from location A9 for the collection period ending 02/17/89 due to the sample line being broken off at the pumphead.

3. Two fish species were not collected from location A and one fish species from location C during February due to adverse river condi tions.

4. The air particulate and airborne iodine sample results from location A8 for the collection period ending 03/30/89 are questionable because the sampler was found with a broken sample line.

A synopsis of the routinely used analytical procedures

, for sample analyses are presented below.

- 2.4.1 Airborne 2.4.1.1 Gross Beta _

~ s The glass fiber filter type A/E (99 percent removal efficiency at 1 micron particulate), _;

is placed into a stainless steel planchet and t_

, counted for Gross Beta radioactivity using a proportional counter. -

2.4.1.2 Gamma Spectrometry j The filters are composited according to ..

station and counted using a germanium detector which is coupled to a computer based, multi-channel analy er. The resulting --

spectrum is then analyzed by the computer and epecific nuclides, if present, identified and quantified. =

2.4.1.3 Strontium-89 and Stro.ntium-90 The composited filters, with stable strontium and barium carriers added, are leached in nitric acid to bring deposits into solution.

After filtration, filtrate is reduced in volume by evaporation. The residue is purified by adding iron and rare earth carriers and precipitating them as hydroxides. After a second strontium nitrate precipitation from nitric acid, the nitrates are dissolved in acid again with added yttrium carrier and are stored for ingrowth period, the yttrium is precipitated as hydroxide and separated from strontium with the strontium being in the supernate. Each fraction is precipitated separately as an oxalate (yttrium) and carbonate (strontium) and collected on a No, 42 (2.4 cm) Whatman m filter. The filters are counted using a low background proportional counter and.the -

Strontium-90 activity is calculated from the oxalate data. The Strontium-89 activity is determined by subtracting the previously calculated Strontium-90 activity from the measured gross Strontium activity calculated from the carbonate.

2.4.1.4 Jodine-131 Each Charcoal cartridge is placed on the i germanium detector and counted. A peak of '

O.36 MeV is used to calculate the ,

concentration at counting time. The j equilibrium concentration at'the end of, gJ collection is then calculated. Decay 34 correction between the end of collection  ;

period and the counting' time is than made. 4 2.4.2 ' Direct Radiation Direct radiation measurements are taken by l' UEC using Thermoluminescent Dosimeters E (TLD's). The UEC program employs the Panasonic Model UD-814 TLD and Model UD-710 g sautomatic dosimeter reader. Each dosimeter g consists of three elements of CaSO 4:Tm and ,

one element of Li B O :Cu. The dosimeters are sealed in a mbikture resistant plastic bag and placed inside a polypropylene mesh cylindrical holder in the environment. After exposure in the environment the dosimeters g-are read and the exposure for the time period 3 is determined from the CaSo g Tm elements.

The Li B o :Cu element is n6t used to '

determ$nk dxposure during routine operations.

2.4.3 Vegetation 2.4.3.1 Iodine-131 A suitable aliquot of wet (as received) 3 sample is placed into a standard calibrated g, container and counted using a germanium

, detector which is coupled to a computer l

based, multi-channel analyzer. A peak of O.36 MeV is used to calculate the concentration at counting time. The equilibrium concentration at the end of E collection is calculated by. decay correcting g between the end of the collection period and the counting time.

2.4.3.2 Gross Alpha and Gross Beta I-A suitable aliquot of ashed sample is l5 transferred to a two-inch ringed planchet. E' The planchet is counted for Gross Alpha and Gross Beta activity using a proportional counter.

2.4.3.3 Gamma __ Spectrometry A suitable aliquot of wet (as r eceived) sample is placed into a standsrd calibrated

( container and specific nuclides, if present,

) identified and quantified using a germanium detector which is coupled to a computer, based, multi-channel analyzer.

2.4.4 Milk 2.4.4.1 ' Iodine-111 Two liters of milk containing standardized Iodine carrier are stirred with anion exchange resin for one hour. The resin is washed with NACL and the todine is eluted with sodium hypochlorite. Iodine in the iodate form is reduced to I and the elementaliodineextracted$ntoCCl back-extracted into water, thenpreh$pitated as palladium iodide. The precipitate is counted for I-131 using a proportional counter.

2.4.4.2 Strontium-89 and Strontium-90 One liter of milk containing strontium and barium carriers is passed through a cation-exchange resin column.

Strontium, barium and calcium are eluted from the cation-exchange resin with sodium chloride solution. Following dilution of the eluate, the alkaline earths are precipitated as carbonates. .The carbonates are then converted to nitrates, and strontium and barium nitrate are precipitated. The nitrate ,

precipitate is dissolved, and barium is '

precipitated as the chromate, purified as the chloride, and then counted to determine the barium 140 (if required). From the supernate, strontium is precipitated as the nitrate, dissolved in water and reprecipitated as strontium nitrate. The nitrate is converted to the carbonate, which is filtered, weighted to determine strontium carrier recovery, and counted for " total radiostrontium" using a proportional counter, 21

I After counting total radiostrontium the second time after six to eight days, Sr-89 concentrations are calculated. If the Sr-89 concentration shows a positive result, the .

precipitate is dissolved, yttrium carrier .

added and the sample is stored for six to  ;

eight days to allow for additional yttrium ingrowth. Yttrium is separated from strontium, precipitated as yttrium oxalate

,and counted to determine Sr-90 concentrations.

The concentration of Sr-89 is calculated as the difference between the activity for l

" total radiostrontium" and the activity due W, to Sr-90.

2.4.4.3 ' Gamma Spectrometry .

3.5 liters or 500 ml aliquot of milk is placed in a standard counting container and specific nuclides identified and quantified using a_ germanium detector which is coupled to a computer based, multi-channel analyzer.

[ yttrium carrier and are stored for' ingrowth of i yttrium-90. The yttrium is precipitated as hydroxide and separated from strontium with the strontium being in the supernate. Each fraction is precipitated separately as an oxalate (yttrium) and carbonate (strontium) and collected on No. 42 (2.4 cm) Whatman filter.

for counting using a low background proportional counter. The strontium-90 concentration is determinec' from the yttrium oxalate counting results and the strontium-89 concentration is calculated as the difference between the strontium carbonate activity and the activity due to strontium-90.

2.4.7.3 Gamma Spectrometry A suitable aliquot of-prepared sample is placed in standard calibrated container and specific nuclides identified and quantified using a germanium detector which is coupled to a computer based, multi-channel analyzer. ,

2.5 Procram Modifications One change to the program was made during 1989. The cow milk sample collected from location M5 was deleted because the cows are no longer used for the production i of milk.

4 4.0 Quality Control Procram i

To insure the validity of the data, the contractor laboratory maintains a quality control (QC) program ,

which employs QC checke, with documentation, of the .

I analytical phase of its environmental monitoring studies. The program is defined in'the QC Program, and procedures are specified in the QC Procedures Manual. t l

The QC Program includes laboratory procedures designed to prevent' cross-contamination and to ensure accuracy and precision of analyses. The quality ~ control checks include blind samples, duplicate samples, and spiked samples as necessary to verify that laboratory analysis activities are being maintained at n-high level of accuracy.

The QC Program is in compliance with USNRC Regulatory Guide 4.15 and includes appropriate control charts with specified acceptance levels for instrument source checks, background, efficiency, etc. for counting equipment.

The Laboratory participates in the USEPA Interlaboratory Comparison Program (crosscheck program) by analyzing radioactive samples distributed for that 1 purpose. The results of the crosscheck program are  ;

presented in Appendix B.

5.0 Data Interpretations In interpreting the data, effects due to the Callaway Plant must be distinguished from those due to other sources.

The principal interpretation method used in assessment of those effects is the indicator-control concept design of the monitoring program at the Callaway Plant.

Most sample types are collected at both indicator locations (areas potentially affected by plant operations) and at control locations (areas.not affected by plant discharge). A possible plant effect would be indicated if the' radiation level at an indicator location was significantly larger than that at the control location. The difference would have to be greater than what could be accounted.for by typical fluctuations in radiation levels ari sing from other sources.

i l

An additional interpretation method ~ involves analysis

for specific radionuclides present in the environmental

( samples collected around the plant site. For certain l isotopes it can be determined if the activity is the +

l 27 '

L t

IL i result of weapons testing or plant operations because of the different characteristic proportions in which ,

these isotopes appear in the fission product mix produced by a nuclear reactor and that produced by a '

nuclear detonation.

Other means of distinguishing sources of environmental l radiation can be employed in interpretation of the 5 data. Current radiation levels can be compared with preoperational; levels. Results can be related to those 3; obtained in other parts of the country. Finally, g results can be related to events known to have caused elevated levels of radiation in the environment.

I, 6.0 Results_and Discussi_on The analytical results for the repoteting period January 3 to December-1989 are present in summary form in 5 Appendix D. For each type of analysisLof each sampled medium, this table shows the annual mean and range for g all indicator locations and for all control locations, The location with the highest annual mean and the g

results for this location are also given.

The discussion of the results has been divided into four pathways; waterborne, airborne, ingestion, and I. i direct' radiation. The individual samples and analyses 3 within each catngory provides an adequate means of g estimating radiation exposure co individuals from the principal pathways. The data for indiv$ dual samples L are presented in tabular form in Appendix E.

6.1 Waterborne Pathway The waterborne pathway of exposure from the Callaway Plant was evaluated by analyzing. surface water, well l

water, washload sediment, bedload sediment, bottom sediment, and shoreline sediment.

Surface Water Analysis for alpha emitters showed detectable activity in thirty-one of the thirty-six samples, with results _

ranging from 1.1 to 6.4 pCi/1, The average sample g concentration at indicator locations was 2.5 pC1/1 and 3 l at control locations was 2.8 pCi/1.. The values are similar to those measured in previous years and can be attributed to natural occurring isotopes.

The average gross beta activity in all surface water samples ranged from 4.5 to 10.4 pCi/ liter. The average E activity was nearly identical 11n both the control 5 locations (7.3 pCi/1) and the indicator locations (7.0 ,

pCi/1) Similar results were obtained in 1983, 1984, 1985, 1986, 1987, and 1988.

28 I  :'

1 The analysis of tritium in surface water showed detectable activity in ten of thirty-six sanples with resulta ranging from 121.0 to 266.0 pC1/1. The mean tritium concentration at indicator locations was 194.5 pCi/ liter and at the control location was 237.8 pCi/1.

The LLDs for the other samples ranged from 145.0 to 500.0 pCi/1. .

There were no gamma emitting nuclides detected in any surface water samples.

Struntium-69 activity was below the detection limit in all samples. Strontium-90 activity was detected in four of the thirty-six samples and ranged from 0.4 to 0.9 pCi/1. The mean sample concentration at indicator locations was 0.5 pC1/1 and at control locations was 0.9 pCi/1.

The levels of act.ivity detected in 'urface water samples during 1989 were consistent with previously accumulated radiological environmen"al data and indicate no influence from plant op" rations.

Well Water In well water samples, gross alpha was detected in twenty-four of thirty-six samples with the results ranging from 1.0 to 3.8 pCi/1. The mean activity for indicator locations was 1.9 pCi/l and for control locations was 2.4 pCifl. Gross beta results showed positive values in thirty-five of thirty-six samples with the results ranging from 2.1 to 14.2 pCi/1. The average activity for indicator locations was 7.3 pCi/1 and for control location was 9.5 pCi/1. The gross alpha and gross beta values are similar to those measured in previouc years.

One sample showed a positive activity for tritium (118.0 pC1/1). All others were below the detection limit which ranged from 149 to 500 pCi/1.

There were no gamma emitting nuclidos detected in any well water samples.

No Strontium-89 activity was observed above the detection limit in any of the well water samples.

Strontium-90 was detected in two well water samples with an average concentration of 0.o pCi/1. Similar Strontium-90 results were observed in 1984, 1985, and 1986. There was no indication of a plant effect on well water.

Washload Sediment

~

All washload sediment samples,showed positive values for gross alpha that ranged from 7602.0 to'14499.0 .

pCi/kg. The average gross. alpha activity for indicator and control locations was 10769.0 pC1/kg and 11110.5 ,

pCi/kg respectively. Gross Beta' activity was dettcted g; in all samples with a range of 22364.0 to 31668.0 g' pC1/kg. The average gross beta activity for indicator- ,

locations was 27310.4 pCi/kg and for the control -

location was 29204.3 pCi/kg.

i One washload sediment sample from a control location showed a positive activity of Cesium-137 (321.0 pC1/kg). All other samples were below the LLO which

-l5'r ranged from 131.0 to 1770.0 pCi/kg. The high LLD were due to low concentrations of suspended solids in the l river.  ;

Due to low suspended solids in river water,  :

Strontium-89 and Strontium-90 analynis was unable to be performed on all but two samples. The results from the two samples were less than the. detection limit. No plant effect was indicated.

Bedload Sediment Detectable concentrations of gross alpha activity were observed in eleven of twelve bedlead sediment samplos with the results ranging from 3158.0 to 15325.0 pCi/kg.

The mean activity for indicator locations was 10235.4 l,'

pCi/kg and for the control location was 9166.3 pCi/kg. m' Gross beta activity was detected in all samples with- 3; results ranging from 15810.0 to 32157.0 pCi/kg. The g1 average gross beta activity for indicator and control  ;

locations was 26096.1kg and 22548.8 pCi/kg respectively.

I Gamma Spectrometry detected Cesium-137 activity in five of the twelve samples. The mean activity at indicator l; locations was 177.7 pct /kg and 236.5 pCi/kg at the 3' control location. The highest Cesium-137 activity, i 356.0 pCi/kg, was detected at the control location A, 1 0.6 miles upstream of discharge. -l Strontium-89 and Strontium-90 analysis was performed on six of the twelve samples. The other samples were of insufficient sample size for analysis. Strontium 89 4 was below the detection limit in all samples.

Strontium-90 activity was detected in.three indicator 3 samples with an average sample concentration of 18.8 g pCi/kg.

30 I

~

The activities detected in bedload sediment samples during 1989 were similar to those measured in previous years and there was no indication of an effect from

- plant operatier.s.

Bottom Sediment

{ Gross alpha analyses of bottom sediment showed positive values for nine of the twelve samples. The alpha activity ranged from 2752.0 to 16123.0 pCi/kg. The average gross alpha activity for indicator locations was 9598.3 pCi/kg and for the control location was 4441.5 pC1/kg. Gross beta activity was detected in all samples with the results ranging from 12069.0 to 31005.0 pCi/kg. The mean beta activity for indicator and control locations was 22352.0 pC1/kg and 15398.5 pCi/kg respectively. The location with the highest mean alpha (10539.8 pCi/kg) and beta (24968.0 pCi/kg) was indicator location D, 59.5 milen downstream of the discharge.

Cosium-137 activity was detected in six indicator locations with a mean concentration of 346.7 pC1/kg.

The range of results was 70.0 to 228.0 pCi/kg.. The location with the highest mean (185.0 pC1/kg) was indicator location D.

Strontium-89 was below the limits of detection in all samples. Strontium-90 activity was indicated in six of

'ihe eight samples from indicator locations, results ranged from 8.5 to 21.1 pCi/kg and averaged 15.0 pCi/kg. The levels of activity are within the range of activities observed during preoperational monitoring.

No plant effect was indicated, Shoreline Sediment Shoreline Sediment sample collections were made in May and November 1989 and analyzed for gamma emitting isotopes. Cesium-137 was detected in the samples collected in May and was 95.0 pCi/kg at the indicator location and 61.0 pCi/kg at the control-location.

There were no gamma emitting nuclides detected in shoreline sediment samples collected in November.

Similar levels of activity were observed in 1984, 1985, and 1987.

6.2 Airborne Pathway The airborne pathways of exposure from Callaway Plant were evaluated by analyzing samples of air particulate and air iodine cartridges.

31

i I;

l Airborne Particulate The gross beta activity ig airborne particulate ranged I from 0.005 to 0.052 pCi/m in all samples. The average gross beta w3s similar at both indicator locations 3 (0.025 pCi/m ) and the control location (0.024 3

pC1/m ). -

The highest annual average (0.026 pCi/m ) was measured E' at indicator location A1, 1.3 miles ENE of the plant. 5 Gamma spectral analysis of quarterly composites of air a; particulate filters showed beryllium-7 in all samples.

The average beryllium-7.agtivity for indicator E'

locations was 0 066 pCi/m and for control the location 3 E_j was 0.061 pC1/m . The presence of beryllium-7 can be attributed to cosmic ray activity. No other gamma- E emitting isotopes of interest were detected in the 1 quarterly compositen. g l,

The Strontium-89 and Strontium-90 analyses performed on the quarterly composites showed in all activities to be below their respective detection limits.

Levels and distribution of activity in the air particulate samples are similar to the previously E accumulated data and indicate no influence from the g plant.

Airborne Iodine Airborne iodine-1313 results were below the detection limit of 0.07 pCi/m in all samples. Thus, there was no indication of a plant effect.

6.3 Incestion Pathway a l',

Potential ingestion pathways of exposure from Callaway Plant were evaluated by analyzing samples of milk, fish, vegetation, and soil. ' ,i Milk A total of twenty-five analyses for iodine-131 in milk were performed during 1989. All samples were below the .

LLI. which ranged from 0.2 to 0.6 pCi/1. sm l Naturally occurring potassium-40 was the only gamma E' emitting isotope found in milk samples. Concentrations ranged from 980.0 to 1910.0 pCi/1. The average i concentration at the indicator location (Goats milk) i was 1711.5 pCi/l and at the control location (cows milk) was 1171.5 pCi/1.

32 II 1 i

l Strontium-89 results were below the LLD for all samples. The LLDs ranged from 0.5 to 1.6 pCi/1.

Strontium-90 was detected in all milk samples averaging 8.1 pC1/1 at the indicator location (Goats milk) and 4.8 pC1/1 at control location (Cows milk). The range of detectable results was 1.8 to 12.0 pCi/1. The average Strontium-90 activities detocted during 1989 show an increase over the average activi ties detected in 1982 through 1988. However, the range of activities are similar to activities detected in 1982 and 1983.

An investigation into the increased Strontium-90 concluded that the activities detect ed were likely from past nuclear weapons test fallout. This conclusion is based on the fact that Callaway plant gaseous effluent samples did not indicate any Strontium-90 activity above the detection limi t of 1.0 E-11 uCi/ml. Starting in 1989 milk samples were analyzed by a different laboratory which could also explain some of the difference.

Calcium was analyzed in all milk samples with levels ranging from 0.55 to 1.28 gm/1. Tho average calcium concentration at the indicator location was 1.03 gm/l and at the control location was 0.9n gm/l.

In summary, the milk data for 1989 show no radiological effects from plant operation. The presence of Strontium-90 in milk samples likely exhibit a long range residual effect of previous atmospheric nuclear tests. Trends of Strontium-90 in milk will be watched carefully in the future.

Fish The types of fish species collected during 1989 were:

River Carpsucker, Gizzard Shad, Channel Catfish, Shortnose Gar, Bigmouth Buffalo, Blue catfish, Paddlefish, Longnose Gar, Smallmouth Buffalo, Freshwater Drum, Flathead catfish, Carp, Shorthead Redhorse, Blue Sucker, Goldeye, Largemouth Bass, White Crappie and Bighead Carp.

One nundred-three of one hundred-sixty two samples analyzed for gross alpha showed detectable activity.

Concentrations ranged from 30.0 to 236.0 pC1/kg-wet.

The mean activity at indicator locations was 96.0 pCi/kg-wet and at control location was 83.1 pCi/kg-wet.

All fish samples indicated positive gross beta concentrations with concentrations ranging from 1933.0 to 4888.0 pCi/kg-wet. T'e average beta activity in I

fish was similar for indicator and control locations (2985.1 and 2860.3 pCi/kg-wet, respectively) 33 u

t Potassium-40 was the only gamma emitting isotope detected. The mean potassium-40 activity was 2915.5 l

pCi/kg-wet for the indicator locations and 2757.2 f I pCi/kg-wet for the control location.

No Strontium-89 activity was detected in the fish samples collected during 1989. Strontium-90 activity g was detected in twelve of the one hundred-sixty two g' samples analyzed with the results ranging from 1.6 to 7.0 pCi/kg-wet. The mean concentration at the a indicator, locations was 4.1 pCi/kg-wet and at the g control location was 2.9 pCi/kg-wet.

The activities detected in the fish samples were consistent with the levels and fluctuations of l!

a' previously accumulated environmental data. The Gross Alpha and Gross Beta activity can be attributed to 3, g

o naturally occurring isotopes (e.g. Fotassium-40). The Strontium-90 activity present in some samples can be ,

attributed to worldwide fallout from atmospheric nuclear testing. It therefore can be concluded that ,

the operation of the plant has had no effect on fish samples.

le_cetatiom l

The vegetation samples collecting during 1989 consisted of mustard greens, turnip greens, lettuce, cabbage, and '

spinach.

i l

Oross alpha activity was observed in forty-one of E fifty-one vegetation samples with the results ranging 5 from 50.0 to 387.0 pC1/kg-wet. The average activity for indicator locations was 146.2 pCi/kg-wet and for g the control location was 135.1 pCi/kg-wet. g Gross beta activity was detected in all vegetation samples with the results ranging from 1251.0 to 9574.0 pCi/kg-wet. The average gross beta activity for l

indicator locations was 4154.9 pCi/kg-wet and for the control was 4831.0 pCi/kg-wet.

Iodine-131 activity was below the dntection limit in all samples. .

Naturally occurring potassium-40 was-found in all vegetation samples. Concentration ranged from 1915.0 to 10010.0 pCi/kg-wet and averaged 3912.4 and 4716.7 l' a

pCi/kg-wet at indicator and control locations respectively. All other gamma emitting isotopes were l below their detection limit. .

s s

None of the vegetation sample results show L statistically significant differences between indicator and control locations and the levels of activities were -

~ consistent with previously accumulated data.

L Therefore, no plant effect was indicated.

2 o.11 -

Gross alpha results-ranged from 4490.0 to 9216.0 pCi/kg for all eleven samples. The mean activity for indicator. locations was 6403.3 pCi/kg and for the control location was 8810.0 pCi/kg. Gross beta activity was also detected in all eleven samples ranging from 19570.0 to 25811.0 poi /kg. The average gross beta activities was 21714.6 and 25758.0 pCi/kg at indicator and control locations respectively.

Gamma spectral analysis of the soil samples showed Cesium-137 and Potassium-40 in all samples. Cesium-137 results ranged from 293.0 to 3023.0 pCi/kg. The average concentration was 1573.4 pCi/kg at the _

indicator locations and 293.0 pCi/kg at the control location. Potassium-40 results ranged from 9345.0 to u 14890.0 pCi/kg. The average concentration for indicator location was 10924.9 pCi/kg and for control .

location was 14890.0 pCi/kg.

The Gross Alpha and Gross Beta activity can be attributed to naturally occurring isotopes (e.g.

Potassium-40). The Cesium-137 activity present can be -

attributed to. worldwide fallout from atmospheric nuclear testing. The level of activity and distribution pattern is very similar to previously -

accumulated data and indicate no influence from the plant.

6.4 Direct Radiation f- All TLD results present in this report have been normalized to a 90-day quarter (standard quarter) to eliminate the apparent differences in data caused by variations in length of exposure period.

The range of quarterly TLD results for indicator locations was 12.0 to 21.9 mrem / standard quarter and 15.7.to 18.8 mrem / standard quarter for control-locations. The quarterly TLD analyses yielded an average exposure level of 18.0 mrem / standard' quarter at all indicator locations and an average exposure level.

> of 17.4 mrem / standard quarter at all control locations.

i During the third quarter 1989, monitoring location 28 displayed an abnormal exposure level of 86.2 + 10.3

-mrem / Standard Quarter. This exposure-level is below g the reportable level of 125 mrem / Standard Quarter. An g investigation into this abnormal exposure was unable to determine the exact cause. However, the investigation did conclude that the Callaway Plant noble gas .

E effluents for the third quarter would not have resulted W

, in this exposure level if all of the activity had'been, released to this location. In addition, all of the 3 other TLD'.s located in this sector and adjoining g sectors did not show any increase in their exposure level during this quarter as would be expected if this i was caused by releases from the plant. Therefore, this

, exposure was excluded from average exposure level for t

the indicator locations listed above. .

The annual TLD results ranged from 4.8 to 28.6 mrem / standard quarter. The average exposure levels were nearly identical at the indicator locations and a4 control locations (16.8 mrem / standard quarter and 16.4 g mrem / standard quarter, respectively).

There was no statistically significant difference between indicator and control locations for the TLD's during 1989. The exposure levels were consistent with previously accumulated data and no plant effects were indicated.

~. 1. INTRODUCTION In accordance with Technical Specification 3.12.2, the annual Land Use Census within a 5 mile radius of the Callaway Plant was Performed during July, 1989 by the Union

{ Electric Real Estate Department. Observations were made in each of the 16 meteorological sectors of the nearest milking animals (cows and goats), gearest rgsidence, and the nearest

[. garden of greater than 50m (500 ft ) producing broad leaf vegetation. This census was completed by contacting the families identified in the 1988 census and driving the roads

( within a 5 mile radius of the callaway Plant noting-the location of the above-mentioned items.

1 The results of the Land Use Census are presented in Table 1

[ thru 3 and discussed below. In the tables, the radial direction and mileage from the Callaway Plant containment are presented for each location. The radial direction is one of the 16 different compass points. The mileage was estimated from map position for each location.

2. CENSUS RESULTS 2.1, Milkinc Animals Table 1 presents the locations where milking animals were observed within the 5 mile radius of the Callaway. Plant.

All milking animals, whose milk is not used for. human consumption and/or not yielding milk, are identified on Table 1. There were several changes in the location and number of milking animals observed during the 1989 census.

~

However, none of the changes observed resulted in changes to the current milk sampling locations.

2.2. Nearest Resident Table 2 presents the location of the nearest' resident to the Callaway Plant in each of the 16 meteorological sectors.

There were two changes in the nearest resident noted in the 1989 census. These changes were in the WNW and NW radial direction.

2.3. Vecetable Gardens The2 1ocation of the nearest vagotable garden of greater than 50m producing broad leaf vegetation is presented in Table 3. Several changes were noted in the garden locations during the 1989 census. However, none of the changes noted resulted in changes to the current vegetable sampling locations.  !

Isotopic Detection Limits and-Activity Determinations Making'a reasonable estimate of the limits of detection for a counting procedure or a radiochemical method is usually  ;

Analytical dete.ction limits are governed by a number of factors including:

I

1. Sample Size

2. Counting Efficiency The fundamental quality in the measurement of a radioactive substance is the number of disintegrations per unit time. As with most physical measurement #in I analytical chemistry, it is seldom possible to make an absolute measurement of the disintegration rate, but rather, it is necessary to compare the sample with one I or more standards. The standards determine the counter efficiency which may then be used to convert sample counts per minute (cpm) to disintegrations per minute l (dpm).

5. Time Interval Between Sample Collec t. ion and Counting Decay measurements are useful in identifying certain  ;

short-lived isotopes. This disintegration constant is -!

one of the basic characteristics of a specific-radionuclide and is readily determined, if the l half-life is sufficiently short.

6. Chemical Recovery of the Analytical.. Procedures.

Most radiochemical analyses are carried out in such a way that losses occur.during the separations. These a losses occur due to a large. number of contaminants that '

may be present and interfere during chemical i separations. Thus it is necessary to include a g ~a technique for estimating these losses:in the B j development of'the analytical procedure.  !

The following method was used to determine lower' limit of' detection (LLD) as per NRC Regulatory Guide 4.1, Rev. 1, " Program for Monitoring Radioactivity in the Environs of Nuclear Power Plants", and the NRC Branch Technical Position, November.1979, "An acceptable -

i Radiological Environmental Monitoring Program". The i LLD is defined, for purposes of this guide, as the -g smallest concentration of radioactive material in a g sample that will yield a net count (above system background) that will be detected with 95% '

probability with only 5% probability of falsely -

"real" signal. .

appropriate), rather than on'an-unverified theoretically predicated variance.

I I Definition of the term used in the data tables are as follows:

I Wet Weight A reporting unit used with organic tissue samples such as vegetation and animal samples in which the amount of sample in taken to be the weight as received from the field with no moisture I removed.

Dry Weight A reporting unit used for soil and I

sediment in which the amount of sample is taken to be the weight of the sample after removal of moisture by drying in I pCi/m 3

an oven.

A reporting unit used with air I particulate and radiciodine data which refers to the radioactivity content expressed in picoeuries per cubic meter of air passed through the filter and/or I the charecal trap. Note that the volume is not corrected to standard conditions.

1 Gamma Emitters Samples were analyzed by high resolution or (GeLi) gamma spectrometry. The Gamma Isotopic resulting spectrum is analyzed by a computer program which scans from about I 5? to 2000 kev an- lists the energy peaks of any nuc2~ des present in concentrations exceeding the sensitivity I limits set for that particular exp iriement .

Error Terms Figures following " + " are error terms I based on ecunting uncertainties at the 95 percent confidence ?.evel. Values preceded by the "<" syn lol were below the stated concentration at the 99 percent confidence level.

-l Sen91tivity In general, all analyses meet the B sensitivity requirements of the program as given in Table 3.1. For the fewf samples that do not (because of inadequate sample quantities, analytical interference, etc.) the sensitivity actually obtained in the analysis is given.

EXECUTIVE

SUMMARY

R I. Envi ronmental information on the condition of vegetation at the Callaway site during the fifth year of plant operation was developed through infrared- aerial ' photography, .photointerpretation - and ground truthing of stressed vegetation, vegetation mapping and phytopathological l diagnoses of stressed vegetation during July, August and September 1989.

i Ten terrestrial study plots were photographed with infrared film at a scale of 1" = 250' . Residual lands were photographed at' a scale of 1"

= 1000' . Photointerpretation was performed based upon the differential inf rared reflectance characteristics of healthy versus stressed tree cover. The infrared photographic record was then verified with a ground truthing field inspection. On-site and laboratory phytopathological

] diagnoses were made for stressed vegetation identified from aerial pho-  !

tography. A vegetation map was produced to show the location -of' stressed .

. vegetation.

I found.

No evidence of the effects of drift from the cooling tower was Vegetation stress in the vicinity of the. plant site was found to j a

be caused by natural factors such as oak wi.lt, Dutch elm disease and root '

1 and butt rot. No distributional pattern of these diseases was identified during the study. Therefore, the folicr disease found in the Callaway vegetation during 1989 can be directly attributed to natural causes and not to operation of the Callaway cooling tower. )

1.0 INTRODUCTION

4 1.1 Purpose

.f Union Electric Company (UE), in response to Nuclear. Regulatory

Commission:(NRC) mandate, has undertaken a program to monitor the poten-tial impacts of cooling tower drift on the local flora surrounding; the UE-1 p Callaway Plant' in Callaway County, Missouri. The goals of the program are to establish a record of- baseline and operational phase. vegetation

.I- conditions at. the Callaway Plant site using color -infrared- aerial pho-  ;

tography, to document any naturally occurring vegetation stress, and to-detennine .if any vegetation damage can be attributed- to operation of: the ,

l cooling tower.

this information.

Interpretation of aerial- photographs was used to prepare This was supplemented . by . ground truthing ' to' assure y accurate interpretation of photographs and field phytopathological 4 assessment to identify the causes of any vegetation stress encountered.-

Using these investigative methods,. preoperational baseline environ- j mental infonnation on the condition of vegetation at the Callaway Plant 1

site was developed during July and August,1984.

Observations during the j _

first, second and third years of plant operation were made during August, *

=

i l 1985, July and August 1986, and August,1987. During July, August and September, 1989, monitoring was performed to assess . the condition of. '

vegetation during the fifth year of plant operation. The results of

! these five years of monitoring complement other vegetation monitoring.

undertaken at the study site. Prior to the present program of infrared ,

fl 2.0 STUDY METHODS b

1 Applied Biology, 'Inc. ( ABI)' acted as coordinator for the infra ~ red '

aerial photography, photointerpretation and= ground truthing of stressed vegetation, vegetation mapping 'and phytopathological assessment of stressed vegetation conducted at the Callaway Plant site in 1989.

2.1 Aerial Photography Aerial photography for this project was flown on 28 July 1989 by.

Walker and Associates, Inc. of Fenton, Missouri. - No cloud cover was' pre-  ;

sent.- Atmospheric conditions were haze-and' dust-free. Color infrared t

film was exposed in a Wild RC-8 precision aerial mapping camera with 6 inch focal length lens.- Ten one-hectare terrestrial study plots were 1 photographed with 60 percent forward overlap at a scale of 1" = 250'..

The residual lands of the plant site were photographed with 60 percent forward overlap and 30 percent side overlap at a scale of 1" = 1000'.- :i Overlapping. of photo frames is used to assure adequate coverage that -I avoids any visual distortion or loss of infrared photograph brightness

• that may occur along the edges of an aerial photographic exposure.

s Duplicate sets of positive film transparencies and positive prints were S

produced in 9" by 9" format.

2.2 Photointerpretation I

Analysis of ' color . infrared aerial photographs for tne presence of -

vegetation stress is based upon the changes in infrared foliage .reflec. I li tance that occur 'as a result of plant. stress. A number of technical sources describe .the theory and application of color infrared vegetation j analysis and. were used as a guide for the photointerpretation in this study. plants under -stress due to insect attack, disease or environmen-tal conditions such as drought exhib'.t discoloration of their foliage on E, color infrared film because of loss of reflectance. - This decrease of infrared reflectance occurs when normally highly reflective spongy leaf '

mesophyll cells collapse because of plant ' stress (Colwell, 1956).

f Vegetation color- differences can: be. used to make inferences 'about plant vigor (Murtha,1982; Barrett and Curtis,1976). Healthy deciduous trees are highly reflective of the infrared . light spectrum end appear as red _

and magenta in color infrared photographs. Evergreen pines and ccdars at the site appear in shades of reddish gray. Stressed vegetat' ion, with leaf yellowing apparent in nonnal spectral color photography, appears in-shades of mauve, blue-grey, yellow and white in color infrared pho-tography. When vegetation is dead and dry, it appears as yellow and tan g on color infrared photography. 'g Using these differential reflectances as signature . guides, examina-E tion of photographs was performed with simple magnification. Trees that were possibly in stressed condition were ~ marked on photographic prints for subsequent ground truthing.

' 2.3 Ground Truthing Grotnd truthing of ' stressed vegetation was the- process used - to '

locate (with the aid .of aerial photographs and topographical maps) poten-tially stressed trees ' recorded on aerial photograph prints. The con-  ;

I' dition of these trees and the assessment made during phytopathological

\

investigations were then correlated with the infrared photographic signa-ture in order to identify stressed trees. . Ground truthing took place on 9 and 10 September 1989.

2.4 Vegetation Mapping' '

i After photointerpretation and ground truthing, the locations. of l stressed or dying trees were' plotted. on a map of the Callaway Plant site .

j at a scale of 1" = 2,000' (Figure 1). -Individual stressed'or dying trees i j!

were represented by. an asterisk (*) on the ~ vegetation map. A - con-siderable numaer of the trees that were plotted on the. site vegetation map were inspected for - photointerpretation ground truth correlation and phytopathological appraisal. .

2.5 Phytopathological Investigations 1

Individual trees that were located at the Callaway site from aerial i

photograph plotting were appraised by plant pathologist Ba rbara --Lucas Corwin of Columoia, Missouri. The purpose of this appraisal was to pro-vide diagnoses of the causes of vegetative stress found on specimens at '

the study site. The causes of plant stresses were categorized as ,

environmental, disease, or insect. Plant species vary in their tolerance 5

of, or sensitivity to, adverse conditions brought about by any of the above categories. It is pertinent to note that stress symptoms in plants, especially ' trees, can be very similar among the categories-of causes mentioned above. i

! I Freezing and thawing, drought, flooding, lightning damage, chemical

.l injury, mechanical injury, or high winds are all examples of environmen-tal conditions that can result in stressed plants. These conditions may  !

cause outright death of plants or may stress them to a. point where they

i are unable to withstand invasion by secondary disease organisms or insect pests.

i Disease is a condition in plants: brought about- as a result of inva--

sion of plant tissues by other living microorganisms. Primary diseases, such as oak wilt and. Dutch elm disease (DED), are caused by microorga-nisms that can invade healthy plant tisues. These organisms consume -;

plant-supplied water and nutrient reserves for their own growth, thereby creating a stress on the plant. Secondary diseases, such as maple decline, are caused by " disease complexes" that usually occur-' on plants that have already been stressed from other causes. Disease-complexes are generally caused by microorganisms that by themselves (.nnot invade tissues of healthy plants. When plants are stressed, however, their nor-mal resistance to invasion by insect and disease organisms is towered.

The disease-complex organisms then are able to invade plant tissues, causing further stress and/or death cf the plant.

l

1. , .

I g

Insects may cause direct or indirect damage to plants that may result in stress. Direct damage usually is a result _ of feeding on plant parts such as leaves, bark (cambial layers), wood, or roots. Oviposition (egg-laying) is another type of direct damage that can restrict .the flow of water or nutrients in the planti Insects may also cause indirect damage by serving as vectors of disease-causing organisms; insects feeding on ' diseased plants inadvertently carry spores of disease orga-nisms to healthy plants.

The elements that were analyzed -during diagnoses of stressed tree specimens were: history of forest management practices or herbicide application, site edaphic conditions, condition of - surrounding vegeta-tion, recent meteorological record, and inspection of tree _ leaves, branches, bark and roots. In addition to field observations, standard culturing procedures using twigs and small branches were carried out in the laboratory in 1984 and 1987 in an attenpt; to- recover the causal fungus in cases of suspected fungal infestation. Samples' were plated on two culture media: 1) oak wilt agar (Nutrimigen base) and 2) acid potato-dextrose agar. These laboratory procedures were inconclusive in 1984 and were not repeated in 1985 or in 1986. In 1987, twig samples from two oak specimens were again cultured in an attempt to isolate the causal fungus. The oak wilt fungus _Ceratocystis fagacearum was isolated I in 1987. Further attempts to isolate this fungus were not repeated in 1989.

! 3 . '1 Photointerpretation and Ground Truthing

.Lialysis of color infrared aerial- photographs indicated that: the vast majority of deciduous trees at the Callaway Plant site were in good health as indicated-by their intense magenta reflectance. Certain deci- ,

i duous trees ^ observed across the st'udy site displayed somewhat lighter -

magenta or pink coloration or a light fringed appearance on infrared  ;

aerial photographs. Ground truthing in- 1989 and in previous years has .i revealed these trees to be species such as red maple (Acer rubrum), syca "

more (Platanus: occidentalis), persimmon (Diospyros virginiana), cotton- '

wood (Populus deltoides)' and mulberry (Morus rubra) that were in good. [

health. Such trees possess a somewhat different-infrared color signature than the deep magenta of the oaks and- hickories- that are dominant at the i Callaway site. Deciduous trees that showed signs of' stress reflected in

.i "

shades of. light pinkish mauve, grey and tan on - infrared photography.- ,

These deciduous trees were plotted as . individual stressed or dying trees on the site vegetation map (Figure 1). The distribution of these trees ,

showed no apparent pattern. Ground truthing and phytopathological exami-nation revealed that a variety of stress factors (detailed in Section 3.2) were affecting these trees. During previous years of vegetation monitoring, areas with relatively high densities of stressed, dying or dead deciduous trees were observed on the aerial photographs. These areas were recorded in past years as tree damage zones on the site vege-tation map. Field inspection revealed that these zones were subject to 9

forest management practices carried out by the Missouri Department of Conservation in which less robust tree specimens or undesired species were girdled -by chain saw cutting. The culled dead and dying trees appeared as stressed aggregations on. infrared aerial photography. In an-area to the west of Vegetation Ecology Site 2, numerous trees appear as whitish, barren trunks on infrared aerial photography. These dead trees L

have been left standing on this site for some time and.have been noted in ~

'j the four previous annual reports on aerial . photographic vegetation moni-toring at the Callaway site. This area is not mapped .as a ' tree damage '

zone in this 1989 report since the observed trees at this location have been dead. for several years and the area is now in a process of N regrowth / recovery, in the generally northern and eastern portions of the survey site, tree cutting along the lowland timber edges has recently been performed by the Missouri Department of Conservation. These edge .

l cuttings do not occur as large contiguous areas that can be effectively ,

mapped as tree damage zones on the accompanying map. . This selective  !

cutting has occurred in the general vicinity of Sites 3,4,5,6,8,9 I' and 10.

Healthy eastern redcedar (Juniperus virginiana) and plantation grown-white pine (Pinus strobus), both evergreen species, displayed reddish gray coloration in infrared photography.

The only stressed white pine that was apparent on aerial photographs were specimens located in a cultivated stand just northwest of the complex of power plant buildings.

These stressed pines displayed pinkish tan infrared reflectance. As a whole, the stand of white pine was .in fairly good condition but with some 10 I

I lower branch dieback, perhaps due to crowding and sunlight shading.

Eastern redcedars were in good condition across the study site in general. -

l 3.2 Phytopathological Investigations

\

Oak wilt (0W), a vascular disease caused by the fungus Ceratocystis fagacearum_, was diagnosed as the cause of stress in a number of oak spe-

[

cimens. These, trees were either black oak (Quercus velutina) or white oak (Quercus alba). Diagnoses were based on symptom expression in the field. Symptum development begins in the upper crown of infected trees.

(

Leaves exhibit marginal scorching, a moisture stress symptom, and often fall from the tree. Leaf scorch symptoms develop because the fungus multiplies in the vascular system, effectively blocking the uptake of water. The disease develops rapidly in the red oak group (which includes black oak and shingle oak), spreading throughout the entire tree.

Infected trees in this group are often killed in a single season.

Disease development in white oaks is much slower.

I usually confined to a few branches each year.

Symptom expression is White oaks decline over a period of several years.

Once a tree dies,- the fungus produces mycelial mats underneath the outer bark. The mycelici mats, or " pressure pads", of ten split the bark, exposing the pad surf ace upon which spores are produced. The spores have a fruity odor that is attractive to the sap- and bark-feeding beetles that vector the fungus to healthy trees. Pressure pads are formed in the late summer of death if adequate moisture is available. If moisture is 11 d

I' I

limiting, pads may not form until early spring if at all (Boyce,1957;

• E31nter and Gubler,1973). Invasion of the oak-wilted trees by second6ry ,

disease organisms inhibits pad formation (Shigo, Gubler,1973).

1985; Tainter and l

I-Oak wilt symptoms were observed at Sites 1 and 10. Dutch elm disease (DED), caused by the fungus Ceratocystis ulmi, was identified as the stress factor on American elm (Ulmus americana) trees. Diagnoses were based' on visual symptoms: wilting, dieback of branches, and disco-loration of the vascular system. DED is a vascular disease similar to ,

oak wilt. It has been devastating on American elm (Ulmus americana) and '

other native sper!n because it is caused by an " introduced" pathogen against which native American elms have not developed genetic resistance.  ;

DED was encountered at Site 9. l I;

A third disease that was encountered was root and butt rot. Root '

and butt rot was observed on plantation grown white pine (Pinus strobus)

I]: .

at Site 7. Root and butt rots are caused oy a variety of fungi capable .

of attacking healthy trees and killing the roots aM the living bark of i the lower trunk. Many of the root and butt rot fungi survive as saprophytes in cut stumps. They utilize the stump as an energy source  ;

for growth through the soil until a healthy root is encountered. These J rots are therefore common in logged areas. Above-ground symptoms of root i and butt rot are expressed as branch die-back and sparse, off-color ,

foliage. Fruiting bodies (basidiocarps) of the causal fungt, when they occur, are usually formed in the fall. Decay and discoloration and I;,

12 l

l I

L a

e L

fungal mats can be observed at the base of the trunk and on large roots just under the soil surface.

A summary of site observations is presented below:

l

[

Site 1 The stressed vegetation at Site 1 was located on a northwest-facing B

slope with shallow soil. A large black oak had recently died, with most of the leaves in the upper canopy having already dropped (slide 1-1). In addition, there was a defoliated white oak nearby. In 1987, the causal agent of oak wilt was isolated from branch specimens at this site. On 5 the basis of_ symptoms observed in 1989, oak wilt , appears to remain active. A fungal leaf blotch on the understory hickory was also noted.

] Site 2

{ A large white oak with thinning in the crown was found to have been the victim of a lightning strike (slide 2-1). In addition, there was a dead black oak nearby. The oaks on this site have been in a period of decline over the past several years, with wood rot and storm damage being prevalent. The understory hickory on this site also had a fungal leaf blotch.

Site 3 All of the stressed vegetation at Site 3 was located at the edge of the woods, adjacent to absndoned-field sites. Visual inspection revealed 13

I; I

that the vegetation involved was maple that was bein9 selectively gi rdled. Most of the girdled trees exhibited a bright red early fall coloring and the girdles were evident at the base of the trunks (slides 3-1 through 3-5).

Site 4 The infrared analysis of this site was similar to that of previous

. years; therefore, no on-site inspection was made. I ,

Site 5 I

No stressed vegetation was noted on this site in 1989. Oak wilt symptoms have been present in this area in the past.

Site 6 The stressed vegetation at this site was maple that was being selec-tively girdled. There are no slides of this site, but the symptoms were the same as those on Site 3.

Site 7 I Several white pines located in a plantation were exhibiting browning I

in the upper crown. Rot and butt rot have been active in the plantation.  ;

Several trees adjacent to those showing browning had been broken over (slide 7-1), revealing the rot at the base of the trunk.

l 14 I

B I

Site 8 Several buckeyes in the woods were exhibiting premature fall coloring, a symptom of stress (slide 6-1). The trees were located on a --

shallow slope, and it is likely that the site conditions alone have caused the decline. i.eaf scorch, a symptom of moisture stress, was observed on the understory maple. A juniper locat'ed in an old fence row had recently died. Close examination revealed that the tree had been intentionally girdled, probably several years ago (slides 8-2 and 8-3). -

Site 9 1

A large old silver maple located on an old hoase site continued to '

exhibit symptoms of dieback and decline (slide 9-1). The condition has been ongoing for several years and 15 probably due to a combination of ,

environmental stress and age of the tree. Several catalpa located in an old fence row were exhibiting an off color of the foliage (slide 9-2).

The trees have suffered damage in the past and have exhibited some branch dieback. The off color is 'due in part to the damage and in part to the species, which tends to have a pale yellow green color in late summer.

Another area on this site is characterized as being low and swampy. Elms on this site have been exhibiting symptoms of Dutch elm disease almost -

every year. Dutch elm disease symptoms were again evident (slides 9-3 and 9-4).

Site 10 One of the stressed trees located on this site was a recently dead shagbark hickory (slide 10-1). It is likely that the death was due to 15

I! :

I.

Armillaria root rot. Basidiocarps of tnis root rot fungus were present at the site (slide 10-2). A fungal l'eaf blotch of the understory hickory was also evident on this site (slide 10-3). .

A black oak located along an old fence row was almost defoliated in the upper crown (slide 10-4). The symptoms are suggestive of ' oak wilt.

Another black oak on this site had died recently. Broken branch stubs with fruiting bodies of a wood rotting fungus were evident. There was also a large wound at the base of the trunk. The tree appeared to have been in a state of decline for some time.

4.0 CONCLUSION

S In general, fewer stressed trees were evident in 1989 than in pre-vious years. The two primary disease symptoms noted were oak wilt on Sites 1 and 10 and Dutch elm disease on Site 9. A fungal leaf blotch was noted on many of the understory hickory. Armillaria root rot was con-fimed on a hickory on Site 10 by the presence of basidiocarps of the I fungus. An unidentified ~ root and butt rot is active in a white pine plantation on Site 7. There was no apparent directional pattern to the distribution of diseased and stressed vegetation.

I No directional patterns of stressed vegetation were noted, and no stress symptoms were found to be due to the effects of drift from Ehe cooling tower. Overall, there was a moderate decrease in the number of stressed trees in 1989 as compared to previous years.

I Most of the deciduous tree cover at the Callaway site is healthy and reflects intense magenta on infrared aerial photography. Those specimens that are stressed or dying are recognizable on color infrared photography because of their mauvish pink, grey or tan reflectance. Rather large tree damage zones were observed in previous years where a forest manage-ment program was carried out by the Missouri Department of Conservation.

In these areas the less robust tree spccimens were chain saw girdled for the purpose of selective tree stand thinning. Such tree damage zones i were not observed at the Callaway site in 1989. However, tree cutting along woodland margins has been performed by the Missouri Department of 17

i I! l Conservation in certain northern and eastern areas of the survey site.

Issentially all of the evergreen species at the study site (white pine and eastern redcedar) are in good condition and are recognizable by their reddish grey infrared refl ectance. Stressed evergreens are apparent because of their tan infrared reflectance. j Ii l

1.0 INTRODUCTION

In accordance with Appendix B, Section 5.4.1 of the Callaway Plant Operating License, the following report was prepared by. Union Electric on all= changes in plant design, operation, tests *or experiments which involved a potentially significant unreviewed environmental question in accordance with Section 3.1 of Appendix B.

The report covers all plant modifications /changas I that were completed for January 1, 1989, through December 31, 1989.

I During 1989 there were eleven plant modifications / changes that involved a potentially significant unreviewed environmental question.

The interpretations and conclusions regarding I~ these plant modification / changes along with a description of the changes are presented below.

2.0 ENVIRONMENTAL EVALUf,TIONS 2.1 Callaway Modification Packa.ge..87-3003 2.1.1 Despriotion_pf Change lg This change involved the' installation of piping g and valves to extend the water treatment plant sludge discharge line to lagoon No. 2. This change will allow lagoon No. 2 to receive sludge I from the sludge pump house when lagoon No. 1 is filled.

2.1.2 Evaluation of Chance ,

l I. The installation of the piping and valves did not result in a significant increase in any adverse l environmental impact, since all measurable non-radiological environmental effects were confined to the areas previously disturbed during '

I site preparation and plant construction.

Therefore, this change does not constitute an unreviewed environmental question per Section 3.1 of Appendix B to the Callaway Plant Operating I. License.

2.2 Callaway Modification Packnoe 87-3021 2.2.1 Description of Chance ,

This change involved the installation of a 6,000 '

1 I.

gallon zine chloride storage tank, metering pumps .

and associated piping between the storage tank and j the service water pump bay. This change will j maintain integrity and control corrosior product i buildup in the service water system. ]

The use of zine chloride for corrosion control is not specifically addressed in the Callaway Plant gl Environmental Report or Final Environmental Statement -' Operating License Stage. However, the g!

Missouri Department of Natural Resources (DNR) has approved the use of zine chloride for corrosion-  !

control in the service water system. The l dissolved zine concentrations in the cooling tower blowdown effluent will be less than one ppm. E, Since the DNR controls the chemical release from 3) the Callaway Plant and has approved the use of zine chloride, this change does not constitute an I unreviewed environmental question per Section 3.1 '

i of Appendix B of the Callaway Plant Operating License.

2.3 Callaway Modification Package 87-3063 2.3.1 Description of Change l This change involves bypassing a section of the Techite discharge line under Highway 94 with a  :

coated carbon steel piping and expansion of the l cathodic protection system to this area. This change.was necessary because the original l discharge line was leaking and causing damage to Highway 94. -

2.3.2 Evaluation of Chance ,

The installation of the. bypass piping did not Iz result in a significant increase in any adverse environmental impact, since all measurable non-radiological effects were confined to the area ~,

previously diaturbed during construction of the original discharge line. Therefore, this change 3 did not constitute an unreviewed environmental g question per section 3.1 of Appendix B to the Callaway Plant Operating License.

2.4.2 Evaluation of Chance F

L This change did not result in significant adverse environmental impact, nor a significant increase in effluents. The increase in activity assoc'iated

( with the new RCCAs due to corrosion of plating material was evaluated by Westinghouse to be negligible. .This was consistent with results obtained from other plants which are using the new

[ RCCA's. Therefore, this change does not constitute an unreviewed environmental question per section 3.1 of Appendix B to the Callaway Plant Operating License.

2.5 Callaway Modification Package 88-2014 2.5.1 Description of Chance 1 This change involved the permanent _ installation of' Temporary Modification TM-88-M005 which was 1 I described in the 1988 Annual Environmental Operating Report Section 5.0.

Cathodic protection will also be added to protect the new carbon steel piping. This change is required to replace the original piping which is leaking.

2.7.2 Evaluation of Chance ,

The replacement of the discharge line piping did not result in a significant increased in any adverse environmental impact,'since all measurable non-radiological effects were confined to the area previously disturbed during construction of the original discharge line. Therefore, this change .

i did not constitute an unreviewed environmental question per section 3.1 of Appendix B to the Callaway Plant Operating License.

2.8 ,Callaway Plant Proce. dure CTD-DE-0611 Rev._1 2,8.1 Descriptice of Chat.lge. --,

The procedure was revised to allow the use of NALCO 8131, a Cationic Coagulate, at the water treatment plant in conjunction with NALCO 8103.

2.8.2 Evaluation of Chance The addition of NALCO 8131, which contains ferric sulfate, will have minimal impact on the water ,

treatment plant sludge characteristics due to the high iron and sulfate concentrations normally observed in the Missouri River The NALCO 8131 will be stored in a 300 gallon puetable tank which will be located such that a spill, overflow or other accidents will not allow a release to waters 3

3 of the state or to other NPDES permitted outfalls.

The Missouri Department of Natural Resources has a approved the use of this product. Therefore, this change does not constitute an unreviewed

-g, environmental question per Section 3.1 of Appendix  ;

B to the Callaway Plant Operating License.
